wrangler publish fails when ESModule is used

[Kynson]

Hello,

I got this error when publishing my ESModule project: Cannot read properties of undefined (reading '1')

I reproduce the issue with the following files:

test.js

import './another.js'

console.log('This is a test')

another.js

console.log('This is another module')

wragnler.toml

name = 'test'
type = 'javascript'
account_id = '<ACCOUNT_ID>'
zone_id = '<ZONE_ID>'

compatibility_date = '2021-11-10'

[build.upload]
format = 'modules'
main = './test.js'

And then run npx wrangler@beta publish

The issue does not exist if another.js is not imported. I am not sure this is a bug or it is because v2 is still in beta and ESModule is not yet supported

Thank you.

I can confirm this bug. The error is being thrown here: https://github.com/cloudflare/wrangler2/blob/65f9904936a11dad8fef599242e0590bb5b7431a/packages/wrangler/src/publish.ts#L142

You can work around this by providing the entry-point script at the command line:

npm wrangler publish index.js

I think this might already be fixed in main after #196, but we should verify

[petebacondarwin]

#196 didn't help.

Working on a fix...

Hitting this right now as well. The temp fix doesn't seem to work - same error. Is there another workaround?

[threepointone]

We just published a fix, could you try again with wrangler@beta?

[wesbos]

wow awesome! Worked great - thanks a million

Closing this, working on the reopened issue #78 and the deeper fix with #258.
